What
Claude Code keeps a record of what each model can do. That record now also notes:
- whether the model supports thinking (reasoning before it answers)
- whether it refuses requests that turn thinking off
- whether it limits effort when thinking is turned off
- whether it accepts a temperature setting, which controls how varied its answers are
